When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam through it. At the ...

A model that predicts the radiation pattern from patch antennas in real installations could take the guesswork out of communication device development. A model that predicts the radiation pattern from ...

SO-CALLED extra or forbidden rings have been observed from time to time in electron diffraction patterns, and their origin has been attributed to half-order diffractions or impurities. Cases in which ...

POSSIBILITIES for X-ray crystal structure analysis of proteins are limited by the minimum spacings observed in diffraction. For many proteins, the minimum spacing is about 2.5 A.—a limit which does ...
